The Origins of Endogenous Growth
梳理了汇聚成“内生增长”的两条研究脉络：一条实证研究穷国是否追赶富国，另一条理论研究如何将发现、创新和技术变革纳入总量增长理论，并认为后者影响更深远。
This paper describes two strands of work that converged under the heading of ‘endogenous growth.’ One strand, which is primarily empirical, asks whether there is a general tendency for poor countries to catch up with rich countries. The other strand, which is primarily theoretical, asks what modifications are necessary to construct a theory of aggregate growth that takes the economics of discovery, innovation, and technological change seriously. The paper argues that the second strand of work will ultimately have a more significant impact on our understanding of growth and our approach to aggregate theory.
